DETAILED DESCRIPTION OF THE DRAWINGS

In the following, only certain example embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive.

FIG. 1 shows a flowchart depicting a method for mining an enterprise relationship according to an embodiment of the present disclosure. At 101, acquiring Internet data of multiple types can be acquired. At 102, enterprise names can be identified from the Internet data through the use of an enterprise name identification model. At 103 data mining can performed on the Internet data in a frequent item mining algorithm to obtain relational degrees among the enterprise names. At 104, the enterprise relationship can be extract from the Internet data according to the relational degrees among the enterprise names by an extractor.

In an embodiment of the present disclosure, supported enterprises can include, but are not limited to, an individual proprietorship, a partnership, an enterprise of other types, and the like.

Data in various websites on Internet includes a variety of kinds of information regarding enterprises. A web crawler can be used to crawl Internet data of multiple types from the various websites. Structured data and/or unstructured data may be included in the Internet data of multiple types. The structured data includes data crawled from a particular website, for example, from a national industrial and commercial database. The unstructured data may include data crawled from various websites on the Internet.

In one possible implementation, at 101 at least one of the following can occur. Acquiring administrative data from a government website by a web crawler, acquiring data on news and public opinions from a news website by a web crawler, or acquiring data on public company announcements from a financial website by a web crawler.

The web crawler can acquire a number of different types of data from different sources. A government website may include, but is not limited to, a government website of a respective level, a website of a respective level of Industry and Commerce Bureau, and the like. For example, administrative data such as enterprise registration information, and enterprise credit information might be included on a website of the Industry and Commerce Bureau. The data on news and public opinions on a news website may include a news report on product release, major investments, and changes in personnel organization. The data on public company announcements on a finance website may includes but not limited to a financial report, a board resolution, regulatory information, integrity information, transaction information, and the like.

Based on the Internet data of multiple types on various websites, a more comprehensive data source can be covered, facilitating the obtaining of more comprehensive analysis of enterprise relationships. The above-mentioned government websites, news websites, financial websites and the related data are only examples, but are not intended to limit the types of websites. A specific website can be selected according to actual requirements.

In an embodiment, as depicted by the flowchart of FIG. 2, the method can further includes steps of pre-processing to the crawled data. For example, at 201, text can be extracted from the Internet data by a statistical method based on a document object model (DOM) tree. At 202 a webpage label can be removed from the text. At 203 the text can be segmented into at least one sentence according to at least one punctuation in the text.

Because there can be interference information such as a large number of advertisements and the like in the webpage, it can be helpful to extract the text from the crawled webpage. With reference to FIG. 3, the text can be extracted by a statistical method based on a DOM tree. A document of HyperText Markup Language (HTML) can be represented as a tree structure by the statistical method based on the DOM tree. The Internet data, such as the text in the webpage, can be recorded through each node in the DOM tree. The text can be segmented into at least one sentence based on at least one punctuation mark after a webpage label that is unnecessary is removed from the text, such as lines, color, symbols and the like included in the webpage template. After pre-processing of the Internet data, the interference information may be removed, which can result in reducing the amount of processing required and increasing the processing capability for the processes of name identification, frequent item mining, and relationship extracting.

In an embodiment, processing at 102 can include inputting the at least one sentence into a Hidden Markov model (HMM), a deep neural network model, or a condition random field model in order to identify the enterprise names.

The MINI is a double Markov random process. A transfer process between states in the HMM is unobservable, and the transfer process corresponds to a transferring probability matrix. A certain observation value is generated or accepted during the state transfer, which is also a stochastic process, corresponding to the outputting of a probability matrix of observation values. Therefore, the number of states N, the number of different symbols M that may be output for each state, the state transferring probability matrix, the probability distribution matrix from a state to a certain observation value, and a probability distribution of the initial state can be included in the HMM. The Hidden Markov model for identifying enterprise names can be obtained by pre-training. The at least one sentence is inputted into the MINI to identify the enterprise names.

In an embodiment, processing at 103 can include using the frequent items mining algorithm to perform at least one of obtaining first relational degrees among enterprise names in one text from the Internet data, obtaining second relational degrees among enterprise names in one paragraph of the one text from the Internet data, or obtaining third relational degrees among enterprise names in one sentence of the one text from the Internet data.

Generally, there may be close relationships among enterprise names which appear in the same article, in the same paragraph, or in the same sentence. For example, if two enterprise names appear in the same article, it indicates that there may be a relationship between the two enterprises. Therefore, based on the identified enterprise names, it is possible to determine whether a relational degree between two enterprises is high or low by performing data mining to the Internet data with the frequent item mining algorithm. Particularly, the relational degree between two enterprise names in the Internet data can be obtained according to different granularities. For example, according to the granularities of article, paragraph or sentence, relational degrees among the enterprise names may be obtained. When Company A and Company B appear in the same article, the first relational degree is 0.3; when Company A and Company B appear in the same paragraph, the second relational degree is 0.5; when Company A and Company B appear in the same sentence, the third relational degree is 0.7. When Company A and Company B appear in different articles (paragraphs, sentences) for multiple times, the relational degree between Company A and Company B can be increased.

In addition, after the frequent item mining algorithm is performed, the relational degrees among enterprises can be represented in the form of, for example, an enterprise table. For example, the correspondence between two enterprises for which the relational degree is greater than 0.5 may be saved in the enterprise table, as shown in Table 1 below. For example, all of the obtained relational degrees among enterprises may also be saved in the enterprise table.

TABLE 1 Enterprise name Related company Relational degree A company B company 0.8 D company E company 0.7 L company N company 0.6

In the enterprise table, different types of relational degrees can be recorded according to different granularities, and a total relational degree can be recorded by combining relational degrees of multiple granularities and the occurrence frequency of an enterprise. The values of the above mentioned relational degree are only examples, and are not intended to limit. In actual applications, the calculation method of the relational degree may be set according to a specific scene.

In addition, data pre-processing can be performed to remove unnecessary content in the Internet data before performing the frequent item mining.

In an embodiment, the method can further include pre-establishing an extractor. With reference to FIG. 3, according to different implementations, the extractor may include an extractor based on a rule (or a template) or an extractor based on a machine learning model. Therefore, the extractor can be established by means of any one of the following modes:

In mode 1, an extraction rule of the extractor is pre-established, such that the extraction rule comprises the enterprise relationship corresponding to a particular relational word, and the enterprise relationship comprises at least one of an affiliation relationship, an upstream and downstream dependency, and a business relationship.

The respective enterprise relationships corresponding to certain specific relational words may be preset, and an enterprise relationship may be extracted based on a specific relational word appearing in the Internet data.

For example, “subsidiary” can belong to a specific relational word indicating the affiliation relationship between two enterprises, and the enterprise relationship corresponding to “subsidiary company” may include “XX is a subsidiary of XX”, “XX is the parent company of XX”, and “XX belongs to XX” and the like. When in a webpage, “subsidiary B of A” is included, the enterprise relationship of “B is a subsidiary of A” can be obtained.

For another example: “customer” belongs to a specific relational word indicating the business relationship between two enterprises, and the enterprise relationship corresponding to the “customer” may include “XX is a customer of XX” and the like. When “customer B of A Company” is included in a webpage, an enterprise relationship of “B is a customer of A” may be obtained.

For another example: “income information” and “payment information” in a company's financial report belong to specific relational words which represent the upstream and downstream dependence between two enterprises. According to the “income information” in the company's financial report, “information of a downstream enterprise” can be extracted. According to the “payment information” in the company's financial report, “information of an upstream enterprise” can be extracted so that the corresponding upstream and downstream dependencies can be obtained.

In mode 2, an extractor based on a machine learning model is pre-established, wherein the machine learning model can be constructed in a condition random field (CRF) algorithm.

The CRF algorithm is often used for sequence labeling problems such as syntactic analysis, named entity recognition, and part-of-speech tagging. By inputting a sentence into a machine learning model constructed by CRF algorithm, the subject, predicate and object of the sentence can be obtained by analyzing. When the subject and object are two enterprise names respectively, a predicate may indicate the enterprise relationship between the two enterprises. The enterprise relationship corresponding to the predicate can refer to the enterprise relationship corresponding to the specific relational word mentioned above.

Specifically, enterprises names among which there are high relational degrees, such as respectively greater than 0.7, can be obtained. The obtained enterprise names and related Internet data (such as the pre-processed sentences) are input into an extractor based on a machine learning model, and a more specific enterprise relationship is extracted by the extractor. For example, in-depth and comprehensive enterprise relationships, such as subsidiaries, upstream enterprises, downstream enterprises, customer relations, and involved industries of A company can be obtained.

In the method for mining an enterprise relationship in the embodiment of the present disclosure, a deeper and more comprehensive enterprise relationship can be obtained by performing data mining to Internet data of multiple types by means of an enterprise name identification model. Specifically, not only can the enterprise relationship be obtained from data crawled from a structured data, such as a data from the national industrial and commercial database, but also the enterprise relationship can be obtained from unstructured data such as public opinions, announcements and the like, which can effectively enrich a knowledge graph on enterprises and facilitate to obtain a relationship network on enterprises. For example, the involved industry, the affiliation relationship, the upstream and downstream dependency, and the business relationship of an enterprise and the like can be obtained, which plays an important role in monitoring the risks of the enterprise and the rise and fall of the industry. By using the frequent items mining algorithm, enterprises among which there are higher relational degrees can be further obtained to obtain a more accurate enterprise relationship. Embodiments of the present disclosure can be applied to, for example, a knowledge graph of an enterprise in a marketing cloud.
